Analysis of the Relationship Between Tax Wedge and Unemployment in OECD Countries

This study investigates the influence of the tax wedge on unemployment, focusing on the context of OECD member countries. The concept of the tax wedge encapsulates the gap between the full cost of labor borne by employers and the net earnings retained by employees after deductions for taxes and social security contributions. It serves as a critical indicator of the fiscal burden on labor and its potential distortionary effects on employment dynamics. This disparity comprises components such as income tax, social security contributions, and other compulsory deductions, collectively representing the fiscal burden placed on labor. High tax wedges may increase the cost of employment for employers, negatively affect their decisions to create jobs, and deepen the structural dimension of unemployment. Within this framework, the research conducts an empirical analysis of how the tax wedge correlates with unemployment levels across OECD member states, utilizing panel data spanning from 2000 to 2023. By integrating the LM bootstrap cointegration method developed by Westerlund and Edgerton (2007) with the Pooled Mean Group (PMG) estimator formulated by Shin et al. (1999), the study uncovers a statistically significant and positive association between unemployment rates and two key fiscal variables: the tax wedge and social security contributions. The findings suggest that increases in these labor-related costs consistently contribute to higher unemployment levels across the countries analyzed. These findings underscore the long-term distortionary effects of labor-related fiscal burdens on employment dynamics within the OECD context. These results highlight the importance of implementing more balanced, labor-market-friendly tax reforms that consider the indirect consequences of taxation on employment outcomes.
